Future Developments in OCPP and ISO 15118 Standards

This guide discusses the future of the Open Charge Point Protocol (OCPP) and ISO 15118 standards in the context of electric vehicle (EV) charging. It outlines the digital communication processes that occur between vehicles and chargers, emphasizing the importance of seamless interactions for a successful charging experience. The document details the evolution of these protocols, including upgrades from ISO 15118-2 to ISO 15118-20 and OCPP 1.6J to OCPP 2.0.1, and highlights the challenges faced in achieving interoperability and reliability in e-mobility charging. The guide also identifies eight core challenges that hinder efficient charging, such as complex user experiences and broken digital payment flows. Additionally, it explains the significance of standards like DIN SPEC 70121 and the role of OCPP in facilitating communication between EV chargers and network operators. Recommendations for navigating the transition to these upgraded protocols are also provided, ensuring enhanced user experiences in the future.
